Chartbreaker: Madonna's MDNA falls harder than Lady Gaga's Born This Way did, while Nicki Minaj takes the top in the U.S. and U.K.

In the ultimate twist of "Give Me Some Luvin'" irony, Nicki Minaj has dethroned Madonna from the top of the Billboard 200 chart this week, as Pink Friday: Roman Reloaded easily takes the top spot with 253,000 copies sold, while Madge's MDNA dropped to number eight, selling only 48,000 in its second week.

Never to be outdone by Lady Gaga, Madonna's sales plummet actually beats Gaga's second week drop in sales for Born This Way, when that record dropped from 1.11 million to 174,000 sold on the June 11 and June 18, 2011 charts. Even Lionel Richie's new album of country collaborations, Tuskegee, didn't fall as hard in its second week; it currently sits at number four.

Adele's 21 has managed to inch back towards the top, checking in at number two this week. Rascal Flatts' new offering, Changed, enters at number three. Close but not quite, One Direction's debut, and former chart-topping, album, Up All Night sets its sights back on the top three, inching closer and closer to a return to the top -- Up All Night saw almost a 100 percent sales increase this week, bolstered, largely, from the guys' appearance on Saturday Night Live last weekend.

The remaining top ten of the Billboard 200 is rounded out by Of Monsters and Men's debut, My Head Is An Animal, at number six; The Hunger Games soundtrack at number seven; gospel singer Marvin Sapp's I Win at number nine; and Shinedown's Amaryllis at number ten.

On the U.K. albums chart, Minaj's Pink Friday: Roman Reloaded is doing equally well, taking the top spot in its first week on the chart, followed by Labrinth's Electronic Earth and Adele's 21, which trail at number two and three, respectively. Madonna's MDNA sits at number seven in its second week overseas.

Fun.'s "We Are Young" continues its reign atop the Billboard Hot 100 for a sixth week in a row, while Gotye is hot on the band's heels with "Somebody That I Used To Know," which continues its ascent, selling 311,000 copies this week and climbing one spot to number two. Speaking of songs moving up, One Direction's "What Makes You Beautiful" moves one to number four, while Carly Rae Jepsen's "Call Me Maybe" charts at number six, also up one spot. Meanwhile, Justin Timber -- er, Bieber... Justin Bieber -- loses 50 percent of sales from last week's massive weekend for "Boyfriend" and comes in at number three. Of course, it's a bad time for a new Bieber single, as Jepsen and One Direction are both infringing on the guy's market.

Other notables in the top ten of the Billboard Hot 100 include Nicki Minaj with "Starships" at number five, The Wanted and "Glad You Came" at number seven, Flo Rida and "Wild Ones" featuring Sia at number eight, Katy Perry and "Part Of Me" at number nine (up one from last week) and Kelly Clarkson and "Stronger (What Doesn't Kill You)" at number ten.

Next week we can expect fun. finally to be dethroned by Gotye's "Somebody That I Used To Know," thanks, in large part, to his guest spot on Saturday Night Live scheduled for this weekend. As for albums, it's anyone's game on the Billboard 200 ... except Madonna's. MDNA will continue to sink next week, perhaps even out of the top twenty. With no major releases scheduled for Tuesday, Pink Friday: Roman Reloaded likely will take another week at the top and, with all of its surrounding hype as of late, may even post a sales gain.
